Abstract: Pearl millet is a major cereal crop in northwestern India. The crop is grown in very harsh, arid, dry climatic areas having high temperature and low and erratic rainfall. Its use as food is declining but its use as cattle feed; poultry feed and source of starch in the alcohol industry is increasing. Its fodder is an important source of animal feed particularly in dry months when alternative sources of feed are not available. Field experiment was conducted during 2014-16 at the Research Farm of College of Agriculture, Gwalior, Madhya Pradesh. The experimental soil is alluvial, sandy clay loam in texture. Eight treatments were tested in a randomized block design with three replications. The treatments were RDF (Recommended dose of fertilizer), RDF + Azotobacter + PSB, RDF+ ZnSO4 @ 25 kg/ha + Azotobacter + PSB, RDF + 1 gm Ammo. Molybdate/ kg seed + Azotobacter + PSB, RDF + 5 kg borax/ha + Azotobacter + PSB RDF + FeSO4 @ 40 kg/ha + Azotobacter + PSB, RDF +ZnSO4 @ 25 kg/ha + FeSO4 @ 40 kg/ha, RDF + 5t FYM/ha + Azotobacter + PSB. Plant height ranged from213.7 to 248.7cm. Maximum plant height (248.7cm) was noted under treatment RDF + ZnSO4 @ 25 kg/ha + FeSO4 @ 40 kg/ha. Maximum ear head length (34.4cm) was recorded with RDF + 5 t FYM/ha + Azotobacter + PSB treatments. Grain yield varied from 3193 to 3750 kg/ha under different treatments and the magnitude of increase in yield due to various INM treatments was 4.29 -17.44 % over RDF treatments. Integrations of FYM (5 t /ha) with recommended dose of fertilizers and bio fertilizers (Azotobacter + PSB) produced significantly higher grain yield of pearl millet over T2 (RDF + Azotobacter + PSB) treatment. Among different micronutrients, application of ZnSO4 and FeSO4 gavesignifianr response in terms of grain yield of pearl millet. Application of FYM @ 5 t/ha or ZnSO4 with RDF + Azotobacter+ PSB gave significant increase in N & K content in grain and stover compared to that only RDF + Azotobacter + PSB (T2) treatment. integration of FYM (5 t /ha) with recommended dose of fertilizers and bio fertilizers (T8) recorded significantly higher N, P & K status in soil compared to only RDF(T1) and RDF + Azotobacter + PSB (T2) treatments. Supplementation of FYM with NPK and biofertilizers was beneficial in enhancing the uptake of nutrients by the pearl millet over NPK only. The maximum net return (Rs 18273/ha) obtained from RDF + ZnSO4 @ 25 kg/ha + FeSO4 @ 40 kg/ha (T7) closely followed by (Rs 18137/ha) and (Rs 18025/ha) by T3 (RDF+ ZnSO4 @ 25 kg/ha + Azotobacter + PSB) and T8 (RDF + 5 t FYM/ha + Azotobacter + PSB) treatments. The maximum B:C. ratio (2.27) was obtained from T3 (RDF+ ZnSO4 @ 25 kg/ha + Azotobacter + PSB).
